Plastic and waste production has increased significantly in recent years. According to the various predictions plastic is not slowing down near future. Since 1960, risen 322 million tonnes 2015 expected double next 20 years (Lusher et al., 2017). 2020 statistical data, leading sectors demand are packaging, building construction, with 40.5% 20.4% respectively. In 2019, an estimated 41% of packaging was recycled EU. Despite advantages recycling technologies, there also a number problems. Mechanical refers processing plastics into secondary raw material or products without changing material’s chemical structure. this paper, we focused at problem micro fibre (PMF) waste, which generated during mechanical recycling. The possibilities using PMF for sound absorption applications tested. For primary acoustic characterisation treated thermally bound other materials. controlled parameter density. density changed from 100 300 kg/m3. performed standard transfer function method (ISO 10534-2). performance materials predicted porous Delany-Bazley-Miki model. aim paper gain essential knowledge about find possible application absorption.
